Enhanced Spectral Modeling of Sparse Aperture Imaging Systems

摘要

The remote sensing community continues to pursue advanced sensor designs and post-processing techniques that improve upon the spatial quality of collected overhead imagery. Unfortunately, spaceborne applications frequently encounter launch vehicle fairing and weight constraints that limit the size of the primarily aperture that can be utilized for a given application. Sparse aperture telescopes provide a potential avenue for overcoming some of the size and weight issues associated with deploying a large monolithic mirror system. These telescope systems are constructed of smaller subapertures which are phased to form a common image field and thereby synthesize a larger effective primarily diameter to obtain higher spatial resolution than that achievable with a single subaperture.
